Distribution Characteristics of Structural-Deformed Coal in Southern Shizhuang Block, Qinshui Basin

Article Preview

Abstract:

The research of structural-deformed coal is important in coalbed methane exploitation. Compared with those of undeformed coals, the geophysical logging characteristics of structural-deformed coals show lower amplitude value of deep lateral log (LLD) and density log (RHOB) and higher amplitude value of acoustic log (AC). In the southern Shizhuang Block, the structural-deformed coal is commonly developed, with the thickness ranging from 0.6 to 1.1 m. The thickness of structural-deformed coals accounts for 11.5-18.5% of the total coal thickness. In general, the structural-deformed coals are more developed in the west than those in the east of the study area.
